Abstract

The invention discloses an optical lens accessory, which comprises a cylindrical body and an annular casing. Rotating shafts are arranged on the inner and outer sides of the outer wall of the cylindrical body, and the outer part of the rotating shaft is connected with a rotating gear through a second torsion spring. And the positions on both sides of the rotating gear are engaged with the first tooth block and the second tooth block respectively, the outer bottom position of the protective cover is also integrally installed with a fixed seat, and the bottom of the fixed seat is integrally equipped with a fixed rod, and the fixed rod The outside of the shell is connected to the inner wall of the reserved groove through the first torsion spring, and the reserved groove is provided through the outer top position of the annular shell. During the use of the optical lens accessory, the installation and disassembly of the entire protective lens is very convenient, and the outside of the entire protective lens has good shock resistance during use, and the entire protective lens is subjected to external impact force There will be no serious damage when it is installed, and there will be no loose installation.

Description

technical field [0001] The invention relates to the technical field related to optical lenses, in particular to an optical lens accessory. Background technique [0002] An optical lens is an optical path system composed of a single or multiple concave-convex lenses. According to the imaging principle, the current lenses can be divided into front-projection lenses, rear-projection lenses and image mirrors. Now the society needs to use lenses on top of cameras and microscopes. , and during the use of the lens, a protective lens is generally installed outside the barrel where the lens is installed to protect the entire lens. Therefore, generally speaking, the protective lens is also one of the accessories of the entire optical lens; [0003] Although there are many types and quantities of protective lenses on the market, their functions are relatively single, and their installation methods are also very simple. There are still a large number of defects in the overall use proces...
